Dr Megha A, Dr Malavika, Dr Sindhu A P

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 4, Pages 459-470

Background : Laparoscopic [LC] surgeries or minimally invasive surgeries are associated
with lesser parietal pain and haemorrhage, compared to the open surgeries. However visceral
pain persists. The effect of volume and concentration on intra-peritoneal instillation of local
anaesthetics for pain relief has not been studied . In this study we have compared the intraperitoneal
instillation of local anaesthetic with transversus abdominis plane block (TAP).
This study is aimed at assessing the superiority of effect of volume of local anaesthetic
instilled intra-peritoneally versus TAP block on post-operative pain relief in laparoscopic
cholecystectomy.

Dr. Marie Ninu, Dr. Jagadish Basumatary, Dr. Ashim Saikia, Dr. Sangeeta Deka

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 4, Pages 1863-1871

Background: Caudal blocks have been shown to reliably block dermatomes below the level of the umbilicus (T10–S5) in children <20 kg (∼6 yr of age).  Caudal epidural anaesthesia involves accessing the epidural space through the sacrococcygeal ligament via the sacral hiatus at the base of the sacrum. The aim of this study was to compare the effects of ropivacaine and bupivacaine for caudal anaesthesia in children undergoing lower abdominal surgery.
Methods: After the hospital ethics committee approval, 60 (ASA I–II) children scheduled for lower abdominal surgery were included in this study. The group A (n=30) patients received ropivacaine 0.25% and group B (n = 30) patients received bupivacaine 0.25% via the caudal route. In this study we assessed demographic and clinical characteristics, AIIMS pain score at 1, 2, 4, 8, 12, 16 and 24 hours after operation and level of residual motor block (Modified Bromage Scale) immediately after surgery and at 1, 2 and 3 hours post operatively.
Results: There were no statistically significant differences in AIIMS pain scores between groups A and B at all postoperative time points – 1hr, 2hr, 4hr, 8hr, 12hr, 16hr and 24hr (P < 0.00001). The quality and duration of analgesia were comparable in both the groups. However, degree of motor block was significantly less in the ropivacaine group. After 3 hours there was no significant difference in the level of residual motor block.
Conclusion: The single shot caudal epidural block with 1ml/kg ropivacaine 0.25% is a safe and effective, long lasting dose for postoperative analgesia in paediatric lower abdominal surgery, producing less duration of motor block than bupivacaine 0.25%.

Comparative study between intrathecal bupivacaine 0.5% heavy + fentanyl (0.5 microgram/Kg) versus intrathecal bupivacaine 0.5% heavy + buprenorphine (2 microgram/Kg) in lower abdominal and lower limb surgeries

Dr. Siddhartha Rapolu, Dr. Prathap Sidda

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 2456-2462

Aim: To evaluate the efficacy of the combination of intrathecal bupivacaine 0.5% heavy + fentanyl (0.5 microgram/kg) versus intrathecal bupivacaine 0.5% heavy + buprenorphine (2 microgram/kg) in lower abdominal and lower limb surgeries.
Materials and Methods: A total of 80 patients who underwent lower abdominal and lower limb surgeries were taken up for the study. Patients were randomised into two groups each. Patients allotted with odd numbers were in GROUP F: Bupivacaine +Fentanyl group (n=40) and patients allotted with even numbers were in GROUP B: Bupivacaine + Buprenorphine group (n=40). Group F received 3ml, 0.5% hyperbaric bupivacaine + Fentanyl (0.5mcg/Kg), Group B received 3ml, 0.5% hyperbaric bupivacaine + Buprenorphine (2mcg/Kg).
Results: In the current study, onset of analgesia was significantly earlier due to the addition of buprenorphine. This may be attributed to high lipid solubility and highest affinity for opiate receptors of buprenorphine. Both the groups had the same mean time to achieve motor blockade. Both groups maintained hemodynamic stability which was statistically insignificant. The mean duration of effective analgesia in Group A and group B found significant statistically (p<0.01).
Conclusion: We observed that anaesthesia was superior when buprenorphine is mixed with bupivacaine (0.5%) as compared to bupivacaine with fentanyl. Addition of buprenorphine to bupivacaine 0.5% augments the sensory blockade of local anaesthetics without affecting the sympathetic activity. Thus, it is concluded that intrathecal buprenorphine is suitable drug for post-operative analgesia for caesarean section.

Ropivacaine a better alternative to bupivacaine: A comparative study of 0.75% ropivacaine vs 0.5% bupivacaine for analgesic efficacy under supraclavicular brachial plexus block

Dr. Divya Chandra, Dr. JP Tiwari, Dr. Sritam Mohanty, Dr. Yogesh Kumar Yadav

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 2115-2126

Background and Objectives: Patients undergoing forearm surgeries have benefited considerably with the widespread use of brachial plexus block instead of general anaesthesia. This study was conducted to investigate the efficacy of 0.75% Ropivacaine in supraclavicular brachial plexus block and to compare the results with 0.5% bupivacaine, which is already established as local anaesthetic for regional anaesthesia.
Methods: Sixty patients of ASA-I and II consenting adult patients undergoing elective upper limb surgeries were randomly divided into Group A and Group B. Group A received 30 ml of 0.5% Bupivacaine and Group B received 0.75% Ropivacaine in supraclavicular block after authenticating the position of brachial plexus with nerve stimulator. Patients were monitored for peak onset and duration of sensory and motor blockade and post-operative analgesia using visual analogue scale. Patients were also observed for any complications during the surgery and in the postoperative period. Sensory and motor block peak and duration of analgesia were evaluated statistically using unpaired t-test and p-value <0.05 was considered significant.
Results: There were no significant differences between the study groups with respect to pattern of changes in Heart rate, Systolic blood pressure, Diastolic blood pressure, Mean arterial pressure perioperatively.
Peak sensory blockade was attained faster in Group B (Ropivacaine) i.e. 13.10 ±2.5 minutes compared to Group A (Bupivacaine) i.e. 23.33 ±3.1 minutes which is statistically significant. Duration of sensory blockade was also longer in Group B (Ropivacaine) i.e. 720.66 ±38.09 minutes compared to Group A (Bupivacaine) i.e. 672.66 ±105.95 minutes and is statistically significant. Onset of Motor blockade was faster in Group B (Ropivacaine) i.e. 18.03 ±2.4 minutes compared to Group A (Bupivacaine) i.e. 24.76±3.1 minutes which is statistically significant. Duration of Motor blockade in Group A (Bupivacaine) was 637.100 ±88.72 minutes compared to Group B (Ropivacaine) i.e. 646.17 ±38.07 minutes and is statistically

not significant. Also, the time for demand of rescue analgesics was prolonged in Group B (Ropivacaine) i.e. 752.66 ±40.33 minutes compared to Group A (Bupivacaine) i.e. 694.56 ±106.14 minutes and this difference is statistically significant.
Conclusion: Ropivacaine 0.75% has an added advantage over Bupivacaine 0.5% for Supraclavicular Brachial Plexus block in terms of early onset of sensory and motor blockade, prolonged duration of sensory blockade, and prolonged duration of analgesia leading to lesser requirement of rescue analgesic. The side effects and complications rate are almost negligible in both groups. Thus Ropivacaine even at higher concentrations of 0.75% and 30 ml volume has proven to be an absolutely safe local anaesthetic. So on the basis of our study we conclude that Ropivacaine 0.75% is an excellent choice for local anaesthetic, which provides better and safer regional anaesthesia.

Comparative study of incremental doses of buprenorphine as an adjuvant to 0.5% bupivacaine in lower abdominal and lower limb surgeries done under subarachnoid block

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 2147-2154

Spinal anesthesia can be performed with a wide range of local anesthetic drugs. using local anesthetics alone is associated with a relatively short duration of action.1 Postoperative pain control is a major problem with spinal anesthesia using local anesthetics alone, and thus early analgesic intervention is needed in the postoperative period. Bupivacaine is the local anesthetic most commonly used, although lidocaine, tetracaine, procaine, ropivacaine, levobupivacaine, and prilocaine may also be used. After institutional ethical committee approval, 90 patients aged between 18-60 years undergoing lower abdominal and lower limb surgeries were selected. A detailed history, complete physical examination, and investigations were done for all patients. Informed consent was taken. The study population was divided into 3 groups with 30 patients in each group. The study has demonstrated that increasing the dose of buprenorphine with 0.5% bupivacaine in spinal anesthesia significantly decreases the time of onset of sensory and motor block and prolongs the duration of sensory, motor blockade. The requirement of postoperative rescue analgesia is also decreased as the dose increased.

Intrathecal 0.75% ropivacaine with fentanyl and 0.5% bupivacaine with fentanyl for lower limb surgeries: Changes in blood pressure

Intrathecal hyperbaric bupivacaine for orthopedic surgeries has faster onset but episodes of hypotension, nausea, vomiting is more than intrathecal isobaric ropivacaine. Maximum level of sensory block height is higher with intrathecal bupivacaine compared to ropivacaine in equipotent doses. To detect a significant difference in mean duration of sensory block between groups B (Bupivacaine with fentanyl) and group R (Ropivacaine with fentanyl) with α = 0.05 & power = 80% the minimum number of 40 cases was required in each group. Randomization was done using a random number table generated from computer software and divided into 2 groups of 40 each. The mean of mean blood pressure showed a significant and consistent fall from the baseline after the sub arachnoid block. This fall was seen in both the groups and was statistically highly significant but was clinically within normal physiological limits. Similarly, the difference in the mean of mean blood pressure between the groups were statistically highly significant but were clinically comparable.

Regional anaesthesia techniques have seen numerous modifications over the last few decades with the advent of many newer and safer local anaesthetics. Even with a variety of drugs available, the search for a safer anaesthetic agent has always been given prime importance in all anaesthesia related practices. Till date 0.5% hyperbaric bupivacaine is the most commonly used drug for orthopedic surgeries in spinal anaesthesia. The study was carried out after approval by the institutional ethical committee in the department of Anaesthesiology. Randomization was done using a random number table generated from computer software and divided into 2 groups of 40 each. Group B: 2.5 ml of 0.5% hyperbaric bupivacaine with 25 μg fentanyl, Group R: 2.5 ml of 0.75% isobaric ropivacaine with 25 μg fentanyl. The quality of anaesthesia, as graded by the surgeons, was excellent in 96.66% in both the groups. In only one patient in group R, poor quality of anaesthesia was reported by the surgeon. This patient was well built and there was some difficulty in muscle retraction. Since the patient was comfortable, no supplementation was given and surgery was completed uneventfully.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 299-307

Background: The aim of the study was to compare multi-modal approach with Tramadol suppository
and Ultrasound guided Transversus Abdominis Plane (TAP) Block with Bupivacaine versus Tramadol
suppository alone in providing adequate post-operative analgesia after Caesarean section.
Method: 158 patients, aged between 18 to 40 years with ASA physical status I-II scheduled for elective
caesarean surgery, were enrolled in this prospective randomized comparative study. 79 patients (of Group
A) were given Ultrasound guided Transversus Abdominis Plane Block with Bupivacaine and Tramadol
suppository as post-operative analgesia. The remaining patients were given only tramadol suppository as
post-operative analgesic (Group B). They were observed for 12 hours or till the patient requested for
rescue analgesic. Pain (VAS score), satisfaction (Likert scale), sedation (Four-point sedation scale),
nausea & vomiting (PONV Impact scale) and adverse effects at 3hours, 6hours, 9hours and 12hours postoperatively
were observed and compared in both the study groups.
Results: Both groups were comparable in demographic data. There was a statistically significant
difference between the VAS scores and satisfaction scores with a p < 0.001 between the two groups. No
statistically significant differences in the sedation, PONV or adverse effects were found between the two
groups. In our study, Group A patients who received ultrasound guided TAP block remained painless for
longer period (23hours) than Group B (6.5hours).
Conclusion: In conclusion, our study suggests that Ultrasound guided TAP block significantly improved
postoperative analgesia in women undergoing Caesarean delivery patients.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 308-316

Background and Objectives: Adjuncts to local anaesthetics for brachial plexus block enhances the
quality and duration of analgesia. The purpose of this study was to compare the effects of
dexmedetomidine, when added as adjuvant to bupivacaine, in respect to onset, duration of sensory and
motor block along with duration of analgesia.
Materials and Methods: After informed consent, 60 ASA I and II patients scheduled for
elective/emergency upper limb surgeries under supraclavicular brachial plexus block (under ultrasound
guidance) was randomized were divided into two equal groups-Group A & B. Group A-received
bupivacaine 28 ml (0.25%) & dexmedetomidine 1μg/kg, and Group B-received bupivacaine 28 ml
(0.25%) & 2ml normal saline. Onset and duration of sensory and motor block, duration of analgesia were
studied in both the groups.
Results: Both groups were comparable with regard to age, sex distribution & duration of surgery. There
was no statistically significant difference. Onset of sensory and motor blockade was 9.2±1.6min
and12.8±1.6mins, respectively in group A, while it was 17.7±2.6min and 23.5±1.7min respectively in
Group B, which (p value˂0.001) is statistically significant. Duration of sensory block and motor block
was 648±49.1min 600.2±45.9min, respectively, in group A, while it was 250.5±26.8min and
206.0±19.0min respectively, in group B, which (p value˂0.001) is statistically significant. The duration
of analgesia in group A was 720.8±44.2 min, while in group B, it was 268.9± 23.1min which (p
value˂0.001), is also significant. There were no adverse events noted in either group. All patients were
haemodynamically stable.
Conclusion: Dexmedetomidine when added to bupivacaine in supraclavicular brachial plexus block had
faster onset, greater duration of sensory and motor block and also longer the duration of analgesia, than
in bupivacaine alone.

Manju Lata Shakya, Mona Bhalavi, Sachin Singh Yadav

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 202-209

Background:Transversus abdominis plane (TAP) block is a well-established analgesic
technique for postoperative analgesia in abdominal surgeries.In our study, we
compared the analgesic efficacy of adjuvant fentanyl and tramadol with Bupivacaine in
TAP block following percutaneous nephrolithotomy.
Methods:In this randomized, prospective, controlled study, 90 patients of ASA grade I
and II were divided into three groups; Group A, Group B, and Group C. Surgical
procedure was done under spinal anesthesia.At the end of surgery, we introduced TAP
block unilaterally in the triangle of petit by feeling two pop technique. Group A
received 28 ml of 0.25% bupivacaine with 50 μg of Fentanyl;1 ml normal saline was
added to make total 30 ml, Group B received 28 ml of 0.25% bupivacaine with 100 mg
of tramadol (2ml), and Group C received 28 ml of 0.25% bupivacaine with 2 ml of
normal saline. The primary outcome wasduration of analgesia (time to first rescue
analgesia) and the secondary outcomes were total dose of rescue analgesics and visual
analog scale (VAS) score recorded at 0,2,6,4,8,12, and 24 hr. If VAS score >4 or patient
complained of pain, then injection diclofenac 75mg intravenous was given as rescue
analgesic.
Results:Duration of analgesia was higher with fentanyl than tramadol & normal saline.
It was 7.01±0.176 hrs., 4.89±0.713 hrs. and 3.01±0.125 hrs. respectively with fentanyl,
tramadol, and normal saline. The total dose of rescue analgesic was lower with fentanyl
than tramadol and higher with normal saline. VAS score was also lower with fentanyl in
comparison to tramadol and normal saline.
Conclusion:Postoperatively many adjuvants were added in TAP block to improve the
quality of analgesia but fentanyl prolonged the postoperative analgesia effectively in
comparison to tramadol or plain TAP block.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 1145-1153

Background: Various adjuvants have been used with local anaesthetics in spinal
anaesthesia to prolong postoperative analgesia. Dexmedetomidine, the new highly
selective α2-agonist drug, is now being used as a neuraxial adjuvant. The aim of this
study was to evaluate the onset and duration of sensory and motor block, hemodynamic
effect, postoperative analgesia, and adverse effects of dexmedetomidine, or fentanyl
when given intrathecally with hyperbaric 0.5% bupivacaine.
Materials and Methods: Ninety patients classified in American Society of
Anaesthesiologists classes I and II scheduled for lower abdominal surgeries requiring
spinal anaesthesia were studied. Patients were randomly allocated to receive either 12.5
mg hyperbaric bupivacaine plus 10 μg dexmedetomidine (group D, n=30) or 12.5 mg
hyperbaric bupivacaine plus 25 μg fentanyl (group F, n=30) intrathecal. The control
group received 12.5 mg hyperbaric bupivacaine intrathecally (n=30).
Results: Patients in the dexmedetomidine group (D) had a significantly longer sensory
and motor block time than patients in the fentanyl group (F) and control group (B).
VAS score at rescue analgesia was significantly higher in the control group. Duration of
analgesia was significantly more in the dexmedetomidine, and fentanyl group as
compared to control. The total duration of analgesia was longer with dexmedetomidine
than fentanyl. Sedation scores were significantly higher in the Dexmedetomidine group.
No hemodynamic changes were noted in any group.
Conclusion: Intrathecal dexmedetomidine and fentanyl as adjuvants to hyperbaric
bupivacaine prolong sensory and motor block with minimal hemodynamic instability
and reduced demand for rescue analgesia. Intrathecal dexmedetomidine has a longer
duration of analgesia than fentanyl.

The development of breast cancer in many women appears to be related to female reproductive hormones, particularly endogenous estrogens. Early age at menarche, nulliparity or late age at first full-term pregnancy, and late age at menopause increase the risk of developing breast cancer. In postmenopausal women, obesity and postmenopausal hormone replacement therapy (HRT), both of which are positively correlated with plasma estrogen levels and plasma estradiol levels, are associated with increased breast cancer risk. Most hormonal risk factors have a relative risk (RR) of ≤2 for breast cancer development. The elective Modified Radical Mastectomy procedure was done in standard fashion. Patients in group A (Study group) received intraoperatively instillation of 0.5% bupivacaine into operative bed at the end of surgery. Patients in group B (Placebo group) received intraoperative instillation of normal saline into the operative bed at the end of surgery position. Approval from the ethical committee of the institution was obtained. All the patients were explained about the basis of the study and informed consent were obtained. Patients who received bupivacaine had longer postoperative analgesia when compared with normal saline group.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 1140-1144

Low back pain is the most common problem among chronic pain disorders in middle aged population. Epidural Steroid Injection (ESI) is one of the most commonly performed non-surgical interventions 1. Objective of study is to compare the efficacy of epidural steroid injection with & without Bupivacaine for low backache patients.
Materials and Method: Two groups of 12 selected patients with chronic low backache were randomized for midline Inter laminar Epidural injection with 80 mg Methylprednisolone acetate with saline and Methylprednisolone acetate 80mg with 0.25% Bupivacaine. All patients received 3 injections at intervals of 2 weeks. They were assessed for degree and duration of analgesia (VAS) and any adverse effects.
Results: Onset of pain relief was less in adjuvant group when compared to non-adjuvant group after ESI. VAS at the end of 6 weeks in both groups was almost same in both groups. There were no significant adverse effects.
Conclusion: Epidural Steroid Injections significantly reduce radicular pain more with Bupivacaine.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 1155-1161

For decades, lignocaine was the local anaesthetic of choice for spinal anaesthesia in ambulatory surgeries. Its advantages are rapid onset of action and good motor block manifested as good muscle relaxation. Its use has become limited because of transient neurologic symptoms and cauda equina syndrome following intrathecal injection. After obtaining the approval of scientific, ethics committee and written informed consent, a total of 100 patients undergoing elective lower limb surgeries under spinal anaesthesia were selected. Patients were explained before operative procedure. Pre-anaesthetic check- up was carried out preoperatively with a detailed history, general physical examination and systemic examination. Airway assessment and spinal column examination was done. In the present study it was observed that there was a statistically difference in the bromage score between groups, score 2 was significantly higher in group II, score 3 was significantly higher in group I p < 0.05. In the present study it was observed that Mean time (in minutes) to pass urine was significantly lower in group I than compared to group II p <0.05.

The lipophilic portion is essential for anaesthetic activity and therapeutically useful local anaesthetics require a delicate balance between lipid solubility and water solubility. Addition of a butyl group to the Piperidine nitrogen of Mepivacaine results in bupivacaine, which is 35 times more lipid soluble and has a potency and duration of action three to four times that of Mepivacaine. Inclusion criteria were American Society of Anaesthesiologists (ASA) physical status I or II, either sex, age 18-60 years, presenting for lower limb surgeries. Exclusion criteria were patient allergic to drug, heart block/dysrhythmia. Hundred slips were made in such a manner that fifty slips had Group 1 written on it and the other fifty had Group 2. In the present study it was observed that there was no statistically significant difference in distribution of patients based on ASA grade in between the two groups p >0.05. In the present study it was observed that there was there no statistically significant difference in adverse events in between group.

Sirisha T, Varaprasada Rao T

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 1193-1200

Introduction: Peripheral nerve blocks are the preferred choice of anaesthesia for surgeries involving the extremities of the human body, with fewer complications. Earlier, the most common drug to be used for the brachial plexus block was bupivacaine, but of late, levobupivacaine and Ropivacaine are used as substitutes to counter the toxicity by Bupivacaine.
Materials and methods: 100 patients aged between 18-60 years with ASA I and ASA II undergoing bony surgeries were randomly divided into Group L and Group R. Group L was given 30 ml of 0.5% Levobupivacaine and Group R was given 30 ml of 0.5% Ropivacaine. Results: The onset of the sensory blockade was significantly lesser in Group L (4.51 ± 0.45 minutes) rather than Group R (5.95 ± 1.33 minutes) while there was no significant difference in the onset of the motor blockade (8.13 ± 2.46 minutes in Group L and 8.42 ± 2.51 minutes in Group R). The duration of the sensory blockage was significantly more in Group L (11.13 ± 2.11 hours) than Group R (9.04 ± 1.42 hours) while there was no difference in the duration of the motor blockade. The duration of analgesia was 11.43 ± 2.17 in Group L and 8.23 ± 1.72 hours in Group R, which was statistically significant.
Conclusion: Since the onset is shorter and duration of anesthesia and analgesic is more effective in Levobupivacaine, it can be used as a preferred drug.

Boini Chiranjeevi, Sarpatwar Sailesh

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 4738-4748

Background:Aim: To evaluate and compare the following factors in two groups –
intrathecal dexmedetomidine and intrathecal buprenorphine as an adjuvant to 0.5%
hyperbaric bupivacaine for lower abdominal surgeries and lower limb surgeries.
Materials and Methods: A clinical study was undertaken to compare the effects of
intrathecal Buprenorphine and dexmedetomidine as additives to 0.5 % hyperbaric
bupivacaine for spinal anaesthesia. This prospective, randomized, Double blind study
was conducted on 60 adult patients of ASA physical status 1 and 2 in the age group of
18 to 60 years, posted for elective lower abdominal surgeries at Osmania Medical
college Hospital, Hyderabad from the period 2017 – 2020. Patients were randomly
allocated into two groups namely, Group BB and Group BD of 30 each. Patients in
Group BB received 60mcg of Buprenorphine with 0.5% bupivacaine 15mg
intrathecally. Patients in Group BD received 5mcg of Dexmedetomidine with 0.5%
bupivacaine 15mg intrathecally. After connecting monitors, the required preloading
done to all patients. Subarachnoid block was carried out under aseptic precautions.
Pulse rate, respiratory rate, arterial blood pressure and oxygen saturation were
recorded at 0, 2, 5 minutes and thereafter every 10 minutes up to 90 minutes
intraoperatively.
Results: The following parameters were observed - onset and duration of sensory block
and motor block, time for sensory regression to S1, degree of sedation, hemodynamic
stability and any side effects associated with these drugs. Collected data were analysed
using appropriate statistics. Demographic datas were not statistically significant. The
onsets of sensory and motor blockades were not statistically significant. The duration of
sensory blockade was prolonged in dexmedetomidine group (51%) compared to
buprenorphine group. The Motor blockade, sensory regression to S1 were also got
prolonged in Dexmedetomidine group Hemodynamic parameters were comparable
between the groups. In our study The onsets of sensory and motor blockades were not
statistically significance between the groups. The duration of both sensory and motor
blockades were prolonged in dexmedetomidine group compared to buprenorphine
group with the best statistical significance. Both groups had stable and comparable
hemo dynamics during the study. Compared to buprenorphine, intrathecal
administration of dexmedetomidine as additive to hyperbaric bupivacaine was
associated with fewer side effects.
Conclusion: Our study concludes that dexmedetomidine as an adjuvant to intrathecal
bupivacaine prolongs both sensory and motor block duration with fewer side effects
compared to buprenophine.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 4804-4813

Background: Various adjuvants have been used with local anesthetics in spinal
anesthesia to avoid intraoperative visceral and somatic pain and to provide prolonged
postoperative analgesia.
Aims: To compare the intraoperative effects of a single low dose of intrathecal tramadol
and intrathecal fentanyl with hyperbaric bupivacaine hydrochloride.
Materials and methods: Fifty patients undergoing Orthopaedic Surgery were randomly
allocated to two groups to be given the following agents by intrathecal route: Group A:
0.5% Bupivacaine 3.0 ml and 25 micro grams fentanyl and Group B: received 0.5%
Bupivacaine 3.0 ml and 25 milligrams tramadol. Intraoperative hemodynamics, pain
scores (assessed using a visual analogue scale), post-operative pain relief and side effects
in both groups was evaluated clinically.
Results: Intraoperatively no significant differences in BP, pulse rate and respiratory
rate were noted. Time to full motor recovery was not delayed in any of the patients in
both the groups. The mean duration of analgesia did not differ in both groups. Mean
duration of analgesia in Group A was 562 minutes and in Group B was 551.2 min. Time
for two segment regression did not differ in both the groups. The patients in both the
groups showed minimal side effects, like nausea, vomiting and pruritis. The incidence of
side effects were statistically in significant.
Conclusions: Both intrathecal tramadol and intrathecal fentanyl act synergistically to
potentiate bupivacaine induced sensory spinal block. Excellent surgical anesthesia and
an extended analgesia was observed in post-operative period with minimum side effects
were observed in both groups.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 5330-5339

Background: Caudal epidural anaesthesia blocks dermatomes below the level of the umbilicus  in children.
Objectives:This study intends to compareropivacaine and bupivacaine for caudal anaesthesia in children undergoing lower abdominal surgery.
Materials and methods: After the hospital ethics committee approval, 60 (ASA I–II) children scheduled for lower abdominal surgery were included in this study. Group A (n=30) patients received ropivacaine 0.25% and group B (n = 30) patients received bupivacaine 0.25% via the caudal route. We assessed the demographic and clinical characteristics, AIIMS pain score at 1, 2, 4, 8, 12, 16 and 24 hours after operation and level of residual motor block (Bromage Scale)immediately after surgery and at 1, 2 and 3 hours post operatively.Data analysis was performed using one way ANOVA test.P value less than 0.05 was considered significant.
Results and conclusion: There were no statistically significant differences in AIIMS pain scores between groups A and B at all postoperative time points –1hr, 2hr, 4hr, 8hr, 12hr, 16hr and 24hr(P < 0.00001). The quality and duration of analgesia were comparable in both the groups. However, degree of motor block was significantly less in the ropivacaine group. After 3 hours there was no significant difference in the level of residual motor block.
The single shot caudal epidural block with 1ml/kg ropivacaine 0.25% is a safe and effective, long lasting dose for postoperative analgesia in paediatric lower abdominal surgery, producing less duration of motor block than bupivacaine 0.25%.

Ashok Rout, Sunny Eapen, Dewendra J Gajbhiye, P Ansuman Abhisek, Pradeep Kedar

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 1499-1506

Background: Opioids and local anaesthetics act synergistically and it’s a popular technique to combine bupivacaine and fentanyl in spinal anaesthesia for caesarean delivery. The aim of the study was to find out optimal dose combination of bupivacaine and fentanyl for spinal anaesthesia for better quality of perioperative analgesia and reduction of feto-maternal adverse outcome during caesarean section.
Methods: Three hundred and four parturients scheduled for caesarean delivery were randomly allocated to four groups of 76 each. Data of 298 parturients (Gp I=73, Gp II=75, Gp III=75 and GP IV=75) was included in the primary outcome analysis. The control group received 12 mg of 0.5% hyperbaric bupivacaine for spinal anaesthesia. Fentanyl 15, 20 or 25 μg was added to each study group who received 9 mg of 0.5% hyperbaric bupivacaine in spinal anaesthesia. Onset and duration of spinal anaesthesia, hemodynamic parameters, intraoperative nausea & vomiting (IONV), failed block, APGAR score and other side effects were noted.
Results: The duration of effective and complete analgesia was significantly longer in all fentanyl groups. However, increasing the dose of fentanyl from 15 to 25 μg had little effect on further prolongation of analgesia. Duration of motor blockade was significantly prolonged in control group. The incidence of hypotension and IONV episodes were significantly low in the study groups.
Conclusion: Bupivacaine and fentanyl have super additive effect in spinal block. However, strict drug dose calculation is required in spinal anaesthesia to minimize adverse outcomes during caesarean delivery. Spinal anaesthesia with fentanyl 15 μg and 0.5% hyperbaric bupivacaine, 9 mg provides optimal surgical conditions for caesarean delivery with negligible side effects as compared to other dose combinations.

Caesarean sections are routinely done under spinal anaesthesia using 0.5% hyperbaric bupivacaine that has a long duration of action. As most of the caesarean sections are of short duration, we decided to compare 1% 2-chloroprocaine with routinely used bupivacaine as chloroprocaine has rapid onset of action, producing an excellent sensory and motor blockade. After ethical committee clearance and informed written consent, 70 uncomplicated singleton parturients of ASA I and II posted for elective caesarean section were randomised into chloroprocaine (CP) and bupivacaine (B) group of 35 each.
Onset of sensory block in group CP was 1.71±0.62min and in group B was 2.31±0.63min. Onset of motor block in group CP was 2.54±0.88min and in group B was 2.66±0.76min. Mean time for maximum sensory block in group CP was 12.77±3.52min and in group B was 22.34±6.46min and time for maximum motor block in group CP was 9.14±2.23min and in group B was 10.86±2.18min. Two segment regression time in group CP was 39.34±4.46min and in group B was 63.14±4.7min. Mean duration of sensory block in group CP was 2.08±0.25hr and in group B was 3.60±0.27hr and duration of motor block in group CP was 1.07±0.14hr and in group B was 3.42±0.41hr. VAS scores in first 6hrs were lesser in group CP than group B. Onset, maximum time, duration of sensory and motor block were lower in group CP than group B. hemodynamic parameters were comparable between the groups with no side effects.

Comparison of Effectiveness of 0.5% Bupivacaine with Neostigmine and 0.5% Bupivacaine Alone in Spinal Anaesthesia for Infra Umbilical Surgeries at a Tertiary Care Hospital

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 5719-5723

Introduction: Pain is the fifth vital sign and a critical focus of the anaesthesiologist. Pain
is perhaps elaborated as an unpleasant sensory and emotional experience associated
with actual or potential tissue damage. Acute post operative pain is a complex
physiological reaction to tissue-injury, visceral distension or disease. It is manifested by
autonomic, psychological and behavioural responses that result in patient specific
unpleasant, unwanted sensory and subjective emotional experience. Postoperative pain
leads to delayed mobilization and its associated complications. With the development of
an expanding awareness of the epidemiology and pathophysiology of pain, more
attention is focused on the multimodal management of pain to improve the quality of
pain relief, augment functionality, leading to early mobilization, and reduce
physiological and emotional morbidity. Hence the present study was done at our
tertiary care centre to compare the effectiveness of intrathecal neostigmine (50 mcg)
combined with 0.5 % bupivacaine (Hyperbaric) with 0.5 % bupivacaine (Hyperbaric)
alone in spinal anaesthesia for infra umbilical surgeries.

Assessment of Post-Operative Pain after Spinal Anaesthesia with 0.5% Bupivacaine Combined with Neostigmine and 0.5% Bupivacaine alone in Infra Umbilical Surgeries

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 5812-5817

Introduction: Stress factors in the operation room and block level mismatch with
surgical area may contribute to discomfort, anxiety and restlessness in patients under
spinal anaesthesia. Sedation is a valuable tool to provide general comfort for the patient.
It usually provides freedom from specific discomfort and can impose some amount of
amnesia for the block procedure and surgical procedure. Thus, legal use of sedation can
make these surgeries under spinal anaesthesia more comfortable for the patient, the
surgeon and the anaesthetist. Therefore, it can enhance the patient's acceptance of
regional anaesthetic technique. Spinal anaesthesia itself can impart some sedative
effects.Spinal subarachnoid block is one of the most versatile regional anaesthetic
techniques available these days. Regional anaesthesia usually offers several advantages
over general anaesthesia—blunts stress response to surgery, decreases intraoperative
blood loss, lowers the incidence of postoperative thromboembolic events and provides
analgesia in early postoperative period. Subarachnoid block provides profound
anaesthesia for patients undergoing infraumbilical surgery.

To assess the efficacy of bupivacaine against levobupivacaine in supraclavicular brachial plexus block

Dr. RuchiAgarwal

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 5855-5860

Aim: The purpose of this research is to assess the efficacy of bupivacaine against levobupivacaine in
supraclavicular brachial plexus block.
Methods: The research comprised 100 patients between the ages of 20 and 55 who had upper limb
orthopaedic and soft tissue lesions and weighed more than 61 kilos and had ASA grades I and II. The
first group received 1 ml (100g) dexmedetomidine mixed with 39 ml of 0.5 percentLevobupivacaine.
As an anaesthetic agent, category II received 1 ml of 0.9 percent normal saline and 39 ml of 0.5
percentLevobupivacaine. The heart rate, respiration rate, SBP, DBP, pulse rate, and oxygen saturation
were all monitored and recorded as soon as the patient entered the OT. In the previously secured
intravenous line, ringer lactate was begun. The supraclavicular technique was used to provide brachial
plexus block.
Results: The mean age in categories I and II was 34.25 and 35.87, respectively. Both outcomes were
statistically significant. All research participants in Category I did not need post-operative analgesia,
but all patients in Category II did. In Category I, 28 percent were mildly sleepy, compared to 100
percent in Category I. Both outcomes are statistically significant. In Category I, the average duration
of sensory and motor block was about 4.1 minutes less than in Category II. (5.87 vs. 9.98 minutes)
The onset of motor blockage in Category I was likewise 4.1 minutes sooner than in Category II (8.88
vs 12.96 min). The mean length of sensory block (577 vs 989 min) and motor block (596 vs 988 min)
was 392 minutes shorter in each category. The duration of post-operative analgesia was 404 minutes
shorter in both categories (579 vs 979 min). The findings are all statistically significant.
Conclusion: We believe that in peripheral nerve blocks requiring high amounts of local anaesthetic,
levobupivacaine may be a feasible alternative due to its lower hazardous potential.

Dr . P. Sravani, Dr. Sathish Bobba ,Dr . Sairaj V

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 5943-5951

Introduction: Epidural anesthesia is a type of neuraxial anesthesia; used for anesthesia of
abdominal, pelvic, and lower extremity procedures and, less commonly, thoracic procedures
and as a supplement to general anesthesia for thoracic, abdominal, and pelvic procedures and
for postoperative analgesia following aforementioned procedures.
Aims: A clinical study comparing efficacy of epidural plain Bupivacaine and combination of
Bupivacaine plus Fentanyl in abdominal and lower limb surgeries.
Materials and Methods: The present clinical study has been carried during 2017-2019,The
Study was under taken to compare the efficacy of Bupivacaine and combination of
Bupivacaine with fentanyl regarding onset, duration and quality of analgesia when given
extraduraly.The study was conducted on 100 adult patients of ASA grade Ι and ΙΙ.
Results: The time of onset of analgesia was determined by pin prick method every one
minute till there was absence of pain sensation and maximum sensory blockade. The quality
of analgesia was recorded as excellent, good, fair and poor. Duration of analgesia was
deduced by testing every 15 minutes with pinprick method for return of sensation in two
dermatomes below the highest level of block achieved i.e., 2-segment regression. The
complications were noted.
Conclusion: The onset of analgesia was quick and time for complete analgesia was earlier in
Bupivacaine and Fentanyl combination group when compared to Bupivacainegroup.The
quality of analgesia was excellent in Bupivacaine and Fentanyl group when compared to
Bupivacainegroup.

Firasath, Abhinaya, Raja Shekar Reddy Motkar, Khaja Layeeq Ur Rahman

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 6094-6103

Background:Hyperbaric bupivacaine 0.5% (l0mg) with fentanyl 15mcg(0.3ml) and (2)
Hyperbaric bupivacaine 0.5% (10mg) with clonidine 45mcg. Objectives: The study
compared the onset and duration of action of intrathecal hyperbaric bupivacaine 0.5
percent and fentanyl 15mcg (group-I) to intrathecal hyperbaric bupivacaine 0.5 percent
and clonidine 45 mcg (group-II) in spinal anaesthesia in LSCS. The combination of
bupivacaine with fentanyl or clonidine assists anesthesiologists in alleviating
intraoperative discomfort by delivering superior analgesia to patients without extending
recovery.
Materials and Methods: The study included 80 female patients with ASA grade I (n=40
in each group). The time of onset of sensory and motor block, duration of analgesia, 2-
segment regression, intraoperative discomfort, hemodynamic stability, time to
micturition, visual analogue score, and postoperative analgesic requirements were all
evaluated.
Results: In group II, the onset of sensory and motor block was substantially later than
in group I (p0.001). Hemodynamic alterations did not differ between groups (p>0.05).
Intraoperatively, 1 patient reported pruritis, and 2 patients had postoperative urinary
II78.506.12min and groupII-—121.284.09 min) and regression of sensory level to L2
dermatome (group-I - 142.206.73 min and group II 166.405.79 min) were significantly
longer in group II (p0.001). The duration of analgesia in group II was 210.186.79
minutes, whereas in group II it was 323.5610.53 minutes, which is significant (p0.001).
The VAS scores in group II were considerably lower after 3 hours (p0.05), 6 hours
(p0.001), and 12hours (p0.001).
Conclusion: The addition of intrathecal clonidine 45 mcg to hyperbaric bupivacaine in
spinal anaesthesia gives greater analgesia with less perioperative discomfort, a longer
duration of analgesia, and a reduction in postoperative analgesic requirements.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 1704-1711

Introduction: Spinal anesthesia is most commonly used for lower abdominal surgeries due to its low cost and ease of administration as well as rapid onset of anaesthesia. Adjuvants like Fentanyl and dexmedetomidine are used to accelerate and prolong the anaesthetic effect depending on the purpose. This study was done to compare the effects of intrathecal hyperbaric bupivacaine with fentanyl and bupivacaine with dexmedetomidine for lower abdominal surgeries.

Comparison of the Effects of Midazolam (1mg) and Fentanyl (25 Mcg) as Additives to Intrathecal 3ml of 0.5% Bupivacaine (15mg) For Spinal Anaesthesia

Srikanth Allam, D Amrutha Lakshmi

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 9921-9936

Background:This clinical study was undertaken to compare the effects of intrathecal
midazolam and fentanyl as additives to intrathecal bupivacaine 0.5 % for spinal
anaesthesia.
Materials and Methods: This prospective, randomized, comparative study was
conducted on 100 adult patients of ASA physical status 1 & 2 in the age group of 18
years to 60 years, at MAMATA GENERAL HOSPITAL, KHAMMAM. on patients
admitted for elective surgery from the period october 2017 - september 2019. Patients
belonging to Group A received 3 ml (15 mg) of hyperbaric bupivacaine (0.5 %) + 0.2 ml
(1 mg) of preservative free midazolam + 0.3 ml of normal saline and Group B received 3
ml (15 mg) of hyperbaric bupivacaine (0.5 %) + 0.5 ml (25 μg) of fentanyl. Patients were
preloaded with intravenous Ringer’s lactate solution 15 ml / kg just before
administering subarachnoid block. Subarachnoid block was administered in L3-L4
intervertebral space with 25G Quincke’s needle. Standard monitoring was carried out
in the form of pulse oximetry, ECG and non-invasive arterial blood pressure
monitoring. Pulse rate, respiratory rate, arterial blood pressure and oxygen saturation
were recorded every 5mins for first 10mins, every 10mins for next half an hour and
then every 15mins intra operatively. The following parameters were observed - onset
and duration of sensory blockade, maximum level of sensory blockade achieved, two
segment regression, onset and duration of motor blockade, duration of effective
analgesia and any side effects associated with these drugs like nausea, vomiting,
pruritis, bradycardia, and hypotension. Computer generated randomization was used
to allocate patients into two groups. Statistical analysis was done using T-test and
fischers exact test. P value of less than 0.05 was considered to be significant
Results: The present study concludes that there were no differences in the onset of
sensory and motor blockade, maximum level of sensory blockade achieved, and time for
two segment regression. 25μg intrathecal fentanyl was found to provide a longer
duration of sensory and motor blockade and prolonged the time for first rescue
analgesia as compared to 1mg intrathecal midazolam. There was no significant
difference between the two groups with respect to the occurrence of side effects.
Conclusion: Hence, we suggest that addition of intrathecal fentanyl is excellent additive
to Bupivacaine for prolongation of duration of anaesthesia without any deleterious
effects.

Dr. Arata Kumar Swain, Dr. Suryasnata Sahoo, Dr. Sabyasachi Das

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 2, Pages 1893-1908

Background: Pain has already been accepted as the sixth vital sign. Hence, attenuation of pain and alleviation of human suffering is of paramount importance in respect to the service provided by anaesthesiologists, for whom the patients submit a virtual suicidal note in the form of expressed consent. Hence, the importance of the study is self-explanatory.
Objective: The purpose of this study was to clinically evaluate the efficacy of post-operative analgesia with epidural Bupivacaine with Butorphanol, Bupivacaine with Fentanyl and Bupivacaine with Nalbuphine.
Material & Method: 75 patients belonging to ASA Ι and ΙΙ, undergoing lower abdominal surgeries were divided into three groups.
Group A: 0.125% bupivacaine + 2 mg butorphanol.
Group B: 0.125% bupivacaine + 100 mcg. Fentanyl.
Group C: 0.125% bupivacaine + 10 mg Nalbuphine Under all aseptic conditions patients were given epidural block with loss of resistance technique.
Results & Conclusion: Conclusions are drawn from the Study: Opioid analgesics with local anesthetics are extremely safe, effective and reliable method of postoperative pain relief. Fentanyl produces faster onset of analgesia with fewer adverse effects like sedation, pruritus, and nausea and vomiting than butorphanol and nalbuphine when given epidurally along with 0.125% bupivacaine. Butorphanol administered epidurally has advantage of longer duration of analgesia than fentanyl or epidural nalbuphine with side effects like nausea vomiting and sedation.

Dr. Shivakumara K C, Dr. Vishal

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 1, Pages 212-216

The brachial plexus is enveloped by a fascial sheath, formed by prevertebral and scalene
fascia, extending from the intervertebral foramina to the upper arm. The foramina of a sheath,
at any anatomical point, will allow for the spread of local anaesthetics and subsequent
blockade. Each approach to the brachial plexus impacts specific anatomical areas of the upper
extremity. Patients were kept Nil per orally for 6 hours before the time of surgery and on the
previous night premedicated with Diazepam 5 mg and Ranitidine 150mg. 60 patients ASA I
and ASA II were randomly allocated with sealed envelope method into two different groups
of 30 each. Both observer and participant were blinded. GROUP A- received (n=30) 25 ml of
0.5% bupivacaine, GROUP B-received (n=30) 25 ml of 0.5% ropivacaine. There was no
statistically significant difference in heart rate between both groups (p>0.05). There is no
significant difference of heart rate clinically.

European Journal of Molecular & Clinical Medicine, 2021, Volume 8, Issue 4, Pages 1734-1743

Introduction: Adequate pain control remains a major challenge after ambulatory surgery. Midazolam as adjunct to local anaesthetics in caudal epidural analgesia has been found effective with minimal adverse effects.
Objective: The study was carried out to evaluate the analgesic efficacy of caudal bupivacaine and midazolam in children undergoing genitourinary surgeryfor post operative analgesia and to study the side effects and complications of bupivacaine and midazolam.
Subjects and methods: Sixty children, aged2-12 were randomly selected from routine cases of pediatric genitourinary surgery in NSCB Medical college and Hospital, Jabalpur.Group B receive 0.25% bupivacaine 0.5ml/kg [n=30] and group BM receive combination of 0.25% bupivacaine 0.5ml/kg with 50 microgm/kg midazolam[n=30].Throughout the study period heart rate,arterial BP, respiratory rate were monitored. Postoperative pain was assessed by MODIFIED TODDLER PRESCHOOLER POST OPERATIVE PAIN SCALE [TPPPS].Rescue analgesia was given when pain score was 4 or more than 4. Sedation was evaluated by four point sedation score.
Results: Lowest pain score were observed in BM group. The mean duration of postoperative analgesia in group  B was 7.6+1.5hrs and in group BM was 10.43+0.95 hrs’ which was statistically significant[p<0.05]. There was no significant changes in HR,BP and respiratory rate in both groups. The incidence of nausea and vomiting were equal in both groups. No respiratory depression,motor paralysis or urinary retention in both groups during the period of study.
Conclusion- Caudal administration of bupivacaine , midazolam mixture prolongs postoperative analgesia compare to bupivacaine alone without causing any adverse effects and complications.

European Journal of Molecular & Clinical Medicine, 2021, Volume 8, Issue 4, Pages 1884-1890

Aim: To Compare the Effectiveness of Bupivacaine Versus Levobupivacaine in
Supraclavicular Brachial Plexus Block.
Material and methods: This cross sectional comparative study conducted on 100 patients of
ASA I & II status in the age group of 20-58 years given brachial plexus block by
supraclavicular approach for various upper limb surgeries, were included in this study.
Result: There was no statistically significant difference between two groups in
demographic data i.e. age, gender, weight, ASA status. The mean onset time of sensory
block was 11.98 minutes in group B & 10.03 minutes in group L while the mean onset time
of motor block was 13.9 minutes in group B & 12.01 in group L. Mean onset time of
sensory and motor block were significantly shorter in group L than in group B. The mean
duration of sensory block was 878.88±118.55 minutes in group B & 1029.35±139.77
minutes in group L while the mean duration of motor block was 929.55±108.58 minutes in
group B & 1111.11±138.65 minutes in group L Mean duration of sensory and motor block
are significantly longer in group L that in group B. The mean duration of analgesia was
911±118.27 minutes in group B and 1068.69±151.47 minutes in group L . The mean
duration of analgesia was significantly prolonged in group L compared to group B.
Conclusion: We concluded that levobupivacaine has a faster onset of both sensory and
motor blockade as compared to racemic bupivacaine. Also, the duration of both sensory
and motor block is longer with levobupivacaine.
